Etienne Bergeron 9d26599078 [clang-tidy] Cleanup some ast-matchers and lift some to utils. 
Summary:
Little cleanup to lift-out and to remove some frequently used
ast-matchers.

Some of theses matchers are candidates to be lifted to ASTMatchers.h.

Etienne Bergeron 1f696b316c [clang-tidy] Add new checker for suspicious sizeof expressions 
Summary:
This check is finding suspicious cases of sizeof expression.

Sizeof expression is returning the size (in bytes) of a type or an
expression. Programmers often abuse or misuse this expression.

This checker is adding common set of patterns to detect some
of these bad constructs.


Some examples found by this checker:

R/packages/ifultools/ifultools/src/fra_neig.c
```
        /* free buffer memory */
        (void) mutil_free( dist_buff, sizeof( ctr * sizeof( double ) ) );
        (void) mutil_free( nidx_buff, sizeof( ctr * sizeof( sint32 ) ) );
```


graphviz/v2_20_2/lib/common/utils.c
```
static Dtdisc_t mapDisc = {
    offsetof(item, p),
    sizeof(2 * sizeof(void *)),
    offsetof(item, link),
    (Dtmake_f) newItem,
    (Dtfree_f) freeItem,
    (Dtcompar_f) cmpItem,
    NIL(Dthash_f),
    NIL(Dtmemory_f),
    NIL(Dtevent_f)
};
```


mDNSResponder/mDNSShared/dnsextd.c
```
	context = ( TCPContext* ) malloc( sizeof( TCPContext ) );
	require_action( context, exit, err = mStatus_NoMemoryErr; LogErr( "AcceptTCPConnection", "malloc" ) );
	mDNSPlatformMemZero( context, sizeof( sizeof( TCPContext ) ) );
	context->d		 = self;
```
